How does Reverse Osmosis Work?

The key concept behind the approach is to eliminate all the organic and inorganic solids dissolved in water. This is achieved through a number of well-structured semi-permeable membranes in which the water under pressure is pushed through.

Some of the impurities found in water that is removed through the process include Flouride, detergents, chlorine, nitrate compounds, sulfate compounds, and lead.


Basic Components of the Reverse Osmosis System

The basic components of the ROS that give us the results of clean-tasting drinking water:

  • Cold Water Line Valve: It acts as the water source for the ROS system and fits into the cold water supply system.
  • Pre-filters: Most ROS have more than one filter where water from the line valve is first passed. Most of the shifts are majorly comprise sediments and carbon.
  • Reverse Osmosis Membrane: This can be considered as the centerpiece of the ROS since it eliminates a variety of contaminants.
  • Storage tank: The tank hold between 2-4 gallons of water from leaving the membrane.
  • Post filters: These are more of a ‘polish’ that annihilate any remaining traces of odor from the water.
  • Automatic Shut off valve: This blocks the flow of water into the storage tank once filled with water from the membrane.
  • Check valve: It is located at the outlet end and prevents the backward flow of treated water into the storage tank.
  • Flow restrictor: This regulates the rate at which water flows in the ROS by ensuring that there is no application of additional pressure by the flowing water that can rupture the system.
  • Faucet: This is a tap that provides a platform by which the purified water can be drawn for drinking.
  • Drain line: The drain line is the avenue by which water containing impurities is disposed of from the ROS.

What To Look for While Choosing the Best Reverse Osmosis System?
